Shine Muscat
Shine Muscat is a diploid table grape cultivar resulted from a cross of Akitsu-21 and 'Hakunan' (V. vinifera) made by National Institute of Fruit Tree Science (NIFTS) in Japan in 1988. It has large yellow-green berries, crisp flesh texture, muscat flavor, high soluble solids concentration and low acidity. Nomenclature registration number is "Grape Agriculture and Forestry No. 21"「ぶどう農林21号. NIFTS registered Shine Muscat as a plant variety domestically in Japan in 2006, but its international protection lapsed because the variety was not registered for global protection within the six-year UPOV deadline.
By 2012, the variety was effectively treated as unprotected outside Japan, allowing growers in countries such as China and South Korea to propagate it legally without paying royalties. In response, Japan passed legislation in 2021 restricting the overseas sale of seeds and seedlings, enabling developers to designate export destinations to protect their intellectual property. In Japan, Shine Muscat is considered a high-end grape, reportedly selling for up to US$100 per bunch, while production in China and South Korea, with larger cultivation areas, has allowed for more affordable prices and a substantial increase in global market share.
It is a cultivar that was bred at the National Institute of Agrobiological Sciences' grape research center (formerly the Akitsu Branch of the Fruit Tree Experiment Station of the Ministry of Agriculture, Forestry and Fisheries (旧農林水産省果樹試験場安芸津支場) in Akitsu-cho, Higashihiroshima City, Hiroshima Prefecture and is an early maturing variety that ripens in mid-August in Hiroshima, where it was bred.
The Muscat of Alexandria, commonly known as Muscat in Japan, is a grape with good taste and texture, but European grapes, including this species, are prone to cracking and disease in areas with heavy rainfall and are not suited to the Japanese climate, requiring facilities such as glasshouses for cultivation.
Resistant to disease and tolerant of the Japanese climate, American grapes are difficult to bite through and are generally considered to be less palatable than European grapes. It also has a unique aroma called foxy scent.
To improve on these shortcomings, the cultivar Steuben, which has the highest sugar content of all American grapes, and Muscat of Alexandria were crossed, and Grape Akitsu 21 was born.
This Akitsu 21 had a flesh similar to Muscat of Alexandria and was rather large, but it had a not-so-good aroma, a mixture of Muscat and Foxy scents.
Therefore, a large-grained European grape cultivar called "Hakunan" (a cross between Cattacurgan and Kaiji), which was created at the Uehara Grape Research Institute in Yamanashi Prefecture, was crossed with a variety that had the best quality and taste but gave up badly due to skin contamination, and this variety with only Muscat aroma was born.
